Coolio.

I chopped the bit of the frame underlying the controls off into a separate icon.
Now the upper bit of the frame (drag handle) and the part underlying the mov are the only hot bits.
Seems to work OK.

Draw the dragging handle and a transparent rectangle into the icon you use to start the dragging, and handle its events.

Sounds like you're close now

I think I see what's happening.
My frame has a transparent hole in it for the mov/controls.
But that trans part stays hot.

I wanted the user to be able to drag it by the mov as well as frame, so I guess I can chop the lower bit off the frame that is behind the controls  and put in a separate display.

That's why you need a child that starts the drag,

PG
  DIS //handle events on this below
  MOV
  INT
    EVT - onPress forDIS above, PG.startDrag
    --
    MovieControls
    --

Hmm.

Have the multiple objects dragging, but the movie controller is hot as well.

of your own devising?

Make sure they all have the same parent, and drag that, I'd think about using a decision icon's page as the container for your player. Then users can drag that. You could have a title bar icon in the page that starts the drag: draw a rectangle into the page's first display icon, set up event handlers for it, and when you handle onPress / onRelease / onReleaseOutside, start / stop dragging the page itself via the page's ID. Magic.

make sure you handle onRelease and onReleaseOutside: that will nail the not dropping problem.

For multiple objects, I guess loop over an array and startDrag on each item: you want to simultaneously drag several things?

Any best practices?

I have noticed before that if the user drags an object quickly then drops it, the "mouse up" sometimes gets missed and the object(s) will then continue to follow the cursor around.

Any way to avoid all the defensive programming?
